Nice tanks. Btw I see you have a OF Hydra internal filter in your turtle tank -- ever tried it in a fish tank? What's your opinion, do you think that Hydra technology really works? I have one sitting on my shelf for about a year now, haven't used it yet.
Also I saw someone commenting on a YouTube comment that the Hydra unit doesn't work as well horizontally positioned, they said it's better to have it vertical, but not sure if this is true or not.
